I'm afraid the answer is no. Wish I'd had your very valuable information before I ordered the new gauges and senders from American Diesels, but I suspect I'd have to order new stuff anyway. Here's why: I have two helm stations and two engines. The lower helm station water temp gauges have been inoperative since I bought the boat 3 years ago. Both the upper helm station's gauges worked A-OK. Then this past weekend, the port engine gauge at the upper helm failed, the needle pegged on the high side at 220-F. As a precaution I shut down the port engine until I could get back to my slip and trouble shoot the problem. Once home, I switched gauges at the upper helm. I discovered then that the port gauge worked fine, while the former port gauge (now on the starboard side) gave the same faulty indication before the switch. My conclusion, perhaps incorrect, is: (1) the senders must be good, otherwise the upper helm gauges would not have been working just fine until now, and (2) the wiring must be good for the same reason. I'd very much appreciate your thoughts and comments on the above.
